What are the different ways in which a genetic condition can be inherited?
Some genetic conditions are caused by mutations in a single gene. These conditions are usually inherited in one of several patterns, depending on the gene involved:
Patterns of inheritance
Inheritance pattern Description Examples
Autosomal dominant One mutated copy of the gene in each cell is sufficient for a person to be affected by an autosomal dominant disorder. In some cases, an affected person inherits the condition from an affected parent. In others, the condition may result from a new mutation in the gene and occur in people with no history of the disorder in their family. Huntington disease, Marfan syndrome
Autosomal recessive In autosomal recessive inheritance, both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. Autosomal recessive disorders are typically not seen in every generation of an affected family. cystic fibrosis, sickle cell disease
X-linked dominant X-linked dominant disorders are caused by mutations in genes on the X chromosome, one of the two sex chromosomes in each cell. In females (who have two X chromosomes), a mutation in one of the two copies of the gene in each cell is sufficient to cause the disorder. In males (who have only one X chromosome), a mutation in the only copy of the gene in each cell causes the disorder. In most cases, males experience more severe symptoms of the disorder than females.
A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons (no male-to-male transmission)

Answer:
Humans are its only known host
Explanation:
Humans are not the only known host for bacterium<em> Francisella</em>. For example, <em>Francisella</em> species such as <em>Francisella tularensis</em> uses many other organisms as its host.
Some of the non-human host organisms for <em>Francisella tularensis </em>are wild rabbits, most of the domestic and wild animals. The <em>Francisella tularensis </em>serve as causative agent of tularemia in these organisms which is a plague-like disease.

Greetings!
If I had to guess, I'd assume the water went back into the sky, forming into more clouds.
This is called evaporation.
Since evaporation is:
<em>The process of turning form liquid to water vapor,</em>
<em />
We can conclude that after the rainstorm, the water evaporated back into the sky.
Hope this helped!
The correct answer is Operant Conditioning.
Operant Conditioning refers to the process of gaining knowledge of system via which the power of a behavior is modified by using reinforcement or punishment. it's also a method that is used to bring about such learning.
even though operant and classical conditioning both contain behaviors managed by environmental stimuli, they range in nature. In operant conditioning, stimuli present when a behavior is rewarded or punished come to govern that conduct.
Answer:
Option c (No, T cells left from the previous infection can kill any virus.
)
Explanation:
When ever viral infection occur, body's immune system start to fight against it by activating B-cells and T-cells.
B-cells produce antibodies that bind with virus and act as label. This label indicate virus as foreign substance. Hence T-cells recognize it and kill it. Furthermore, B-cells form memory cell that keep the viral memory. if this viral infection occur again in future, T-cell recognize it and eliminate the virus.This mechanism is called immunity.
